FERDINAND H. BERGER, OF 'DETROIT, MICHIGAN, ASSIGNOR TO RUSSEL MOTORCOMPANY, OF DETROIT, MICHIGAN,

A CORPORATION OF MICHIGAN.

GEARING.

Specification of Letters Patent.

Patented Apr. 18, 1911.

To all whom it may concern:

Be it known that I, FERDINAND H. BER- GER, a subject of the Emperor ofGermany, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certain new and useful Improvements inGearsecond, to inclose ing, of which the reference being had therein tothe accompanying drawings.

he invention relates to drive axles for vehicles such as automobiles inwhich a compensating gearing is employed for permitting the relativemovement of the axle wheel.

It is the object of the invention, first, to

obtain a construction of gearing which may be readily removed orreplaced as a unit; said removable unit in an oil tight case, and third,to provide within said housing, substantial bearings for the drive shaftand axle shaft.

With these and other objects in view, the

invention consists in the construction as hereinafter set forth.

In the drawings,-Figure 1 is a horizontal section through thecompensating gearing in the plane of the axle; Fig. 2 is a view of aportion of Fig. 1 showing a slightly modified construction.

A is the axle case which is provided with a central enlarged portion inwhich the compensating gearing is located. B and B are the two axlesections within this case, which engage with the compensating anend-wise movement. gearing comprises gear wheels C, C

gearing by The compensating intermeshing beveled and D which areinclosed within a frame E having enlarged beveled gear wheel F. Thelatter meshes with a beveled pinion G which is driven from the powertransmission shaft of the vehicle (not shown). The frame E is providedwith alined tubular portions H, H which form bearings for the shank I,I, of the gear-wheel O and also journals for the frame and gear wheel F.These journals engage bearings J in an outer housing K which inclosesall of the gearing. The housing K is formed in two separable sectionsdividing in the plane of the axis of the pinion G and these sections aresecured to each other by clamping bolts L. lll are annular flanges onthe housing sections forming races for the bearings J.

N is a bracket arm extending inward from following is a specification,

one of the sections which contains a bearing 0 for the inner end P ofthe shaft of the pinion G. This shaft extends outward and engages inouter bearing Q beyond which is a collar R engaging an annular oil anddust cap S having a threaded engagement with the housing K.

The whole housing K is of such form that it may be inserted through anaperture T in the rear of the casing A, and a flange U preferablyintegral with the housingforms a closing cap for said aperture, and ameans for securing the housing rigidly thereto. The forward end of thehousing is provided with a neck portion V,.which engages a correspondingneck bearing W in the axle case.

The construction as described is one that may be removable from orengaged with the axle case as a unit, it being only necessary to removethe clamping nuts for the flange U and to withdraw the axle sections B Bendwise so as to disengage the same from the pinions C C. The casing isnot only just removable, but forms when removed an oil-tight housinginclosing all of the parts of the mechanism: thus, detachment foradjustment or repair is greatly facilitated.

The important feature of the construction is the manner of forming thebearings for the pinion G. This provides double hearing with the twosections on opposite sides of the pinion and both being preferably ofthe roller or ball type. Roller bearings are also provided for the axlesections.

In Fig. 2 a construction is illustrated in which the pinion and thejournal hearings on opposite sides thereof are removable and adjustableas a unit. In this construction the collar R. instead of directlyengaging the casing K. has a threaded engagement with a sleeve R, andthe latter is threaded 'to engage the housing. The sleeve R also carriestheroller or ball bearing Q, and the inner roller or ball bearing 0 isconnected to move longitudinally with the shaft of the pinion G. Thus,whenever it is desired to remove the pinion, by unscrewing the sleeve Itboth ball bearings and the pinion will be drawn out of the housing. Theconstruction may further be used to adjust the pinion G in relation tothe gear wheel by screwing the sleeve R in or out of the housing. Anysuitable locking means, such as a spring latch X, may be employed forholding the sleeve when adjusted. The ball thrust bearing Y is alsopreferably introduced between the bearing Q, and the collar R. I

What I claim as my invention is:

1. The combination with an axle case, of a compensating gearinginsertible in and removable from said case as a unit, said removableunit including the housing for the parts. 7

2. The combination with an axle case, of a compensating gearinginsertible in and removable from said case as a unit and including anoil tight housing inclosing the parts.

3. The combination with an axle case, of a compensating gearing, and ahousing for said gearing formed of separable sections inclosing all ofthe parts to form a removable unit.

1. The combination with an axle casing, of a compensating gearingincluding a beveled pinion for axial alinement and engagement with thepower transmission shaft, and a housing for said gearing forming abearing for said pinion.

5. The combination with an axle casing, of a compensating gearinginsertible in and removable from said casing as a unit, and a housingfor said gearing formed in sections separable in a central planetransverse to the axle.

6. The combination with an axle case, of a compensating gearinginsertible in and removable from said case as a unit, a housing for.said removable unit formed in sections separable centrally in a planetransverse to the axle, and bearings within said housing for the axleand drive shaft.
